                            PETITION TO DENY OF INMARSAT

       Inmarsat, Inc. (“Inmarsat”) submits the following Petition to Deny in response to the

Federal Communication Commission’s (“Commission” or “FCC”) Public Notice regarding

ViaSat, Inc.’s (“ViaSat”) petition seeking access to the United States for a non-geostationary

(“NGSO”) Fixed-Satellite Service (“FSS”) satellite network involving a constellation of 24

satellites operating in medium earth orbit (“MEO”).1 ViaSat requests to use 27.5-29.1 GHz and

29.5-30.0 GHz FSS “uplink” spectrum and 17.8-19.3 GHz and 19.7-20.2 GHz FSS “downlink”

spectrum for inter-satellite links.2 This proposed operation of inter-satellite links has the

potential to cause harmful interference to other satellite operators. Inmarsat urges the

Commission to deny ViaSat’s request to use the requested bands for inter-satellite links.

       Inmarsat is the leader in global mobile satellite communications, operating a global

system of 13 satellites and associated ground infrastructure that offers a wide range of

communications solutions to customers on land, in the air, and at sea. Inmarsat’s Global Xpress

broadband satellite service uses the Ka-band to deliver data speeds of up to 50 Mbps to the most

remote and inaccessible locations of the world, and along nearly every point of many long-haul

aviation and maritime routes that currently lack high-speed connectivity. Global Xpress is the

result of a $1.6 billion investment that included the launch of four high-bandwidth satellites, and

the construction of an earth station in Lino Lakes, Minnesota. Inmarsat also operates mobile

satellite services supporting critical communications applications requiring up to 99.999%

availability. Inmarsat’s global system allows customers across the aviation, maritime, enterprise

and government sectors to have reliable and assured access to high-throughput communications

including voice, mobile broadband, connected car, Internet of Things, smart society, safety-of-

life, and emergency communications applications. Inmarsat’s Global Xpress satellites operate in

the 17.7-20.2 GHz and 27.5-30.0 GHz bands that overlap with some of the bands ViaSat

proposes to use.

       ViaSat requests market access in the 17.8-18.6 GHz and 18.8-20.2 GHz (space-to-Earth)

and 27.5-29.1 GHz and 29.5-30.0 GHz (Earth-to-space) frequency bands to provide FSS to end

users and seeks to use these same frequency bands for inter-satellite links between the proposed

ViaSat MEO NGSO satellites and its in-orbit GSO satellites. 3 Inmarsat respectfully requests that

the Commission deny ViaSat’s request to use Ka-band spectrum for inter-satellite links as ViaSat

has not provided any demonstration that these proposed operations will be compatible with GSO

FSS networks.

       ViaSat asserts that operation of satellite-to-satellite links between the proposed MEO

satellites and ViaSat’s GSO satellites is consistent with the definition of FSS. Although the

                                                                                                   2


Commission’s definition of FSS contemplates “in some cases” inter-satellite links,4 the Ka-band

FSS allocations are designated for space-to-Earth or Earth-to space communications, not for

space-to-space. Inter-satellite links have the potential to cause interference to other satellite

networks. Even ViaSat acknowledges that operation of these links may not be contemplated by

the Commission’s rules. 5

       ViaSat’s inter-satellite link proposal is a “non-conforming use” because it is inconsistent

with the Ka-band allocations in the U.S. band plan. The Commission requires an applicant

proposing a non-conforming use to demonstrate it will not interfere with authorized services and

must accept any interference it will receive from authorized services. 6 ViaSat in its Application

does not provide or address the showing required for authorization of non-conforming uses.

       Indeed, ViaSat fails to provide analysis that would provide any assurance to the

Commission or GSO FSS operators that the MEO-to-GSO link would not cause interference to

other GSO networks licensed to provide service to the U.S. or other countries. ViaSat asserts

that by the MEO-to-GSO transmission complying with the FCC off-axis EIRP density mask in

Section 25.138 (a)(1)7 and by ensuring that the 3-sigma antenna pointing error is less than 0.2

degrees, compatibility in a 2 degree GSO spacing environment is assured. However, no analysis

is provided on whether a transmitter operating on a MEO satellite at an orbit of 8200 km, as in

                ViaSat seems to propose to only meet the off-axis EIRP limits specified in
25.138(a)(1) for co-polarized signals in the plane tangent to the GSO arc and does not address
the other off-axis EIRP limits contained in Section 25.138.

                                                                                                     3


the ViaSat proposal, will cause the same impact to other GSO satellite as if the transmitter was

on the Earth. While the Commission is considering permitting operation of earth stations on

aircraft in the Ka-bands, 8 aircraft typically have a cruising altitude of 9 to 12 km, which has a

minimal effect on the impact to other GSO satellites compared to the same transmitter on the

Earth’s surface. A transmitter on a MEO satellite would result in a time varying and very

different interference geometry, which should be carefully studied to ensure that GSO satellite

operations are not affected.

       Further, the bands where ViaSat proposes to operate satellite-to-satellite links are highly

utilized by GSO FSS satellites which stand to be joined soon by a plethora of NGSO FSS

satellites. This heavy level of use creates a contested interference environment. ViaSat itself has

raised concerns that the current equivalent power-flux density (“EPFD”) limits, which were

adopted 20 years ago, may not be sufficient to protect current and future GSO FSS satellites.9

Introducing new sources of interference from NGSO-satellite-to-GSO-satellite transmissions

would only exacerbate the potential for interference to GSO FSS satellites.

       Any new use of the Ka-band for NGSO-to-GSO links needs to be carefully studied to

determine if such use will impact existing services both on a single entry and aggregate basis. It

would be naïve to assume that the proposed ViaSat NGSO system will be the only NGSO system

which will seek to communicate with GSO space stations. Since no such analysis has been

provided, the Commission should deny ViaSat’s application for inter-satellite links in the Ka-

band FSS spectrum.

       Finally, as the Commission has recognized, grants of NGSO applications must be

conditioned on the outcome of the FCC’s pending NGSO Rulemaking.10 As the Commission is

aware, there are several sets of NGSO EPFD limits that apply in the bands requested by ViaSat,

including single entry validation and operational limits that must be met by individual NGSO

FSS systems, as well as limits that must be met by all NGSO FSS systems in aggregate.

Inmarsat filed detailed comments in the NGSO Rulemaking urging the Commission to create a

mechanism to ensure that aggregate EPFD limits will be met by all NGSO FSS systems licensed

in a particular band. 11 If the Commission grants ViaSat’s petition (apart from the request to use

the Ka-band for inter-satellite links, which should be denied) prior to the resolution of the NGSO

proceeding, it should condition grant on the outcome of that proceeding. Taking this action is

consistent with the Commission’s recent grant of market access to OneWeb. 12

       For the reasons provided above, Inmarsat requests that the Commission deny ViaSat’s

request to use the Ka-band for inter-satellite links.
